[0003] For example, the authorization announcement number "CN115654197A" is named an electromagnetic air valve. Although the present invention can prevent the fluid in the pipeline from being discharged into the equipment and prevent the fluid from contacting the elastic part, the existing electromagnetic air valve still exists during use. When the fluid flows into the electromagnetic air valve, the sealing part and the outlet are sealed, which can prevent the fluid in the pipeline from being discharged into the equipment installed with the electromagnetic air valve, and isolate the elastic part and the fluid through the sealing part to prevent the fluid from contacting the moving iron core and the elastic part, thereby preventing scale from forming on the surface of the moving iron core and the elastic part. Therefore, it will not affect the movement of the moving iron core and improve the service life of the electromagnetic air valve. Since the elastic part of the electromagnetic air valve is a spring, the spring is prone to aging after long-term use, and the weakened spring elasticity makes it impossible for the seal to be reset, thereby reducing the service life of the electromagnetic air valve.
